The microscopic process of the martensite transformation in a small model crystal with the Lennard-Jones potential is studied by introducing two modifications into the standard molecular dynamical simulation. One is the removal of the kinetic energy at proper intervals corresponding to the latent heat during the martensitic transformation. The other is to follow visually the evolution of numerical results. The visual observation of the nucleation of the martensite in the atomistic scale allows us to follow the process of the gradual evolution of the sharp boundaries from the diffused displacements created around the atom, which is given a finite displacement.
